1 Claim.

This invention aims to provide a simple means whereby a canner or other user of a conveyer can provide himself with a conveying instrumentality of large area, without buying a special conveyer chain, it being possible to attach the device easily and. quickly to the pintle of a conveyer chain, cost being cut down and the weight of the conveyer chain being increased by a very small amount only.

The invention has an another of its objects, the provision of novel means for conveying cans readily through cookers, or for conveying glassware or other material from one machine to another, during packing or other operations.

Another object of the invention is to supply a conveyer which can make a turn of short radius,

thereby changing the direction of the conveyer and making it possible to carry packages or containers back and forth a number of times through a steam box or the like, the entire space in the box being utilized.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it

being understood that changes in the precise embodiment of the invention herein disclosed, may

be made within the scope of what is claimed,

without departing from the spirit of the invention. In the drawings:

Fig. 1 shows in plan, a device constructed in accordance with the invention;

Fig. 2 is a plan wherein the bend of the conveyer frame is included; Fig. 3 is a transverse section of the structure shown in Fig. 1;

Fig. 4 is a vertical elevation; Fig. 5 is a top plan, parts being broken away; 7 Fig. 6 is an enlarged transverse section; Fig. 7 is a transverse section showing one of the disks;

Fig. 8 is a top plan disclosing a modification. The conveyer frame or track may be composed of angle members i having a slot 2 between their horizontal flanges. The conveyer frame may embody a U-shaped bend 3, or any other kind of a bend. A shaft 4 is supported for rotation in the bend 3 and carries a sprocket wheel 5 adapted to cooperate with a sprocket chain which runs on 65 edge, that is, in the vertical position shown in Figs. 3 and 4. The conveyer chain preferablyis an endless chain.

The links of the chain comprise sockets 6 from which transverse arms '5 project, the arms diverging at 8, so that, at their more widely spaced ends, they may span the socket 6 of an adjoining link. One arm has an upstanding boss 9, and the 5 opposite arm has a depending boss it provided with a projection ll received in a slot 12 in the head ill of a pintle l5, to hold the pintle against turning, the pintle passing through the overlapped ends of the arms I of adjoining links, and through 10 the socket 6.

Disks it of thin but strong material, preferably metal, are provided, and have central, depending tubular hubs ll receiving the upper ends, of the pintles l5. Securing elements i8, such 15 as cotter pins, pass through the openings IQ of the pintles l5 and through the openings 20 of the hubs I"! of the disks it, the hubs of the disks preferably resting on the bosses 9 of the links. The disks G6 are overlapped as shown at 20 2 l, and are disposed above the horizontal flanges of the conveyer frame or track made up of the angle members i. The hub ll is disposed out of rightangular relation to the plane of the disk [6,

whereby one disk may overlap another like disk 25 diameters of the disks being increased. In Fig. 8,

parts hereinbefore described have been desig nated by numerals already used, with the 35 suffix a.

The device affords a simple means whereby almost any link chain may be transformed into an efiicient conveyer. Short turns may be made wherever necessary, and the device may be operated in steam or water, without objectionable deterioration.

Although a specific means has been shown for mounting the disks, such as the disks 16, many 45 applications of the invention, not shown in the drawings, are possible.

Having thus described the invention, what is claimed is:

An attachment for conveyer chains, compris- 5 ing a disk having a tubular hub the axis of which is disposed out of rightangular relation to the plane of the diskQwhereby one disk may overlap another like disk when the hubs receive closely the pintles of a conveyer chain.
